Species Ypthima arctous (Fabricius, 1775)

Dusky Knight

Introduction

Orr & Fliedner (2011) suggested that the correct spelling of the species group name is arctoa on the basis that the name is a Latin adjective, meaning pertaining to the north star. However, Braby (2011) questions this interpretation because it is a name in apposition, originally used to describe a place, which therefore should be retained in its original form
